Title | Lunar synchronization of daily activity patterns in a crepuscular avian insectivore | Type | Journal Article | ||
Year | 2020 | Publication | Ecology and Evolution | Abbreviated Journal | Ecol Evol |
Volume | 10 | Issue | 14 | Pages | 7106-7116 |
Keywords | Animals; Moonlight | ||||
Abstract | Biological rhythms of nearly all animals on earth are synchronized with natural light and are aligned to day-and-night transitions. Here, we test the hypothesis that the lunar cycle affects the nocturnal flight activity of European Nightjars (Caprimulgus europaeus). We describe daily activity patterns of individuals from three different countries across a wide geographic area, during two discrete periods in the annual cycle. Although the sample size for two of our study sites is small, the results are clear in that on average individual flight activity was strongly correlated with both local variation in day length and with the lunar cycle. We highlight the species' sensitivity to changes in ambient light and its flexibility to respond to such changes in different parts of the world. | ||||

Title | Illuminating Military Installations | Type | Journal Article | ||
Year | 2020 | Publication | Society of American Military Engineers | Abbreviated Journal | |
Volume | 112 | Issue | 726 | Pages | 66-68 |
Keywords | Lighting; Planning | ||||
Abstract | Military bases must implement high security measures to ensure the safety of personnel and visitors. Lighting is a critical aspect of a base-wide security plan. Installations require high-quality, reliable lighting and real-time reporting and diagnostics so energy and security personnel know when and where luminaires are down and why, allowing them to re-establish the security perimeter more quickly. Modern installations are also concerned with conserving energy and reducing maintenance in order to decrease overall operating costs. An energy-efficient lighting system helps minimize the military’s energy footprint and decrease greenhouse gas emissions. There are, however, challenges associated with these efforts. Most bases sprawl across thousands of acres and include a range of applications that require a broad portfolio of luminaires—from roadways and intersections to security checkpoints, substations, motor pools, and office, housing, and medical buildings. They also include a mix of personnel who reside and work on base. Some military personnel and civilians arrive in the morning and leave at night. Others, including soldiers manning security checkpoints, require illumination for tasks performed after dark. In addition, many installations are located near residential areas or wildlife refuges where sky glow and light pollution must be avoided. | ||||

Title | Literature study: The effects of reduced public lighting on crime, fear of crime, and road safety | Type | Journal Article | ||
Year | 2019 | Publication | west-vlaanderen | Abbreviated Journal | |
Volume | Issue | Pages | |||
Keywords | Safety; Security; Psychology; Review | ||||
Abstract | 1. Introduction 1.1 Stating the problem: security versus climate and economic challenges Public street lighting as a public service is often taken for granted. However, its impact on the nocturnal perception of public space should not be underestimated. It encourages people to get out, feel safe, and be safe. Indeed, Welsh and Farrington suggest that public lighting enhances social control, cohesion, and a feeling of community pride (Welsh & Farrington, 2008b). According to (Williams, 2008), this is due to the special meaning attached to the darkness of night in society. It is associated with changes in social norms and values, transgression, the release of social control, feasting, drinking, and pleasure. Meanwhile, the darkness of night generates unpredictability, uncertainty and, therefore, fear. Illuminating the night chases away these feelings; people feel reassured and safer (Schivelbusch, 1995). |

Title | Spatial Trend Of Light Pollution In Obio/Akpor Lga, Rivers State, Nigeria | Type | Journal Article | ||
Year | 2020 | Publication | International Journal of Novel Research in Civil Structural and Earth Sciences | Abbreviated Journal | |
Volume | 7 | Issue | 2 | Pages | |
Keywords | Lighting; Perception | ||||
Abstract | The study examines the spatial trend of light pollution across the study area. The Global Positioning System (GPS) was used to acquire the coordinates of each respondent resident, where structured questionnaire were administered in the study area and then imported to the ArcGIS 9.3 software environment to analyse the spatial trend in light pollution using the Inverse Distance Weighted (IDW) method of interpolation. Findings, reveals that the perception of pollution by light stray is obviously noticed by the respondents with particular emphasis on light stray from traffic light, neighbor security lights which to a large extend alters their level of comfort and distort their level of outdoor relaxation. Thus, the study recommends, among others, that: shielded light bulbs or properly designed light fittings should be installed to avoid light rays spreading beyond the needed boundaries. And measure should be taken to ensure car drivers use properly fixed headlamps that are not damaged and also, awareness should be passed on adequate use of headlamps by road users (vehicle drivers) on streets when compared with use on highways and minor roads. | ||||

Title | Avoiding room light during night may stimulate immunity in COVID-19 patients by promoting melatonin production | Type | Journal Article | ||
Year | 2020 | Publication | Melatonin Research | Abbreviated Journal | |
Volume | 3 | Issue | 4 | Pages | 476-481 |
Keywords | Human Health; Commentary | ||||
Abstract | COVID-19 is one of the greatest health issues facing humankind for many decades; it emerged in Wuhan, China, late in December 2019, and rapidly spread over the world within the short period. This report emphasizes the potential hazards of exposure to room light at night which affects the immunity of COVID-19 patients by suppressing their melatonin, which is only released from the pineal gland at night. Exposure to light at night is especially common in the hospital setting. This may make the symptom worse for the hospitalized patients and the light at night should not be ignored. Thus, I suggest that COVID-19 patients should avoid light at night either by wearing eye masks or darkening the room to enhance pineal melatonin synthesis and increase their serum melatonin levels. | ||||
